2. Setup Instructions
Setting up your Bell+Howell Ultrasonic Pest Repeller is straightforward. Follow these steps for optimal performance:
- Unpack the Devices: Remove all six pest repellers from their packaging. The kit includes three different sizes: Micro, Standard, and Macro (with an extra outlet).

- Micro Design: Ideal for tight spaces, narrow hallways, and countertops.
- Standard Design: Suitable for medium to large rooms, such as garages or offices.
- Macro Design (with Extra Outlet): Convenient for bedrooms and living rooms, as it provides an additional AC outlet for other electronic devices.
- Plug In: Insert each repeller into a standard electrical outlet. Ensure the unit is not obstructed by furniture, curtains, or other objects that could block the ultrasonic waves.
- Verify Operation: A red indicator light on the front of the unit will illuminate, confirming that the repeller is powered on and functioning.

3. Operating Instructions
The Bell+Howell Ultrasonic Pest Repeller operates continuously once plugged in. It uses intelligent variable technology to emit ultrasonic frequencies that are highly irritating to rodents and insects, causing them to seek a more peaceful environment away from your home.
- Continuous Operation: The device is designed for 24/7 operation. Keep it plugged in at all times for continuous pest defense.
- Silent and Odorless: The ultrasonic frequencies are inaudible to humans and most household pets, and the device emits no chemicals or odors.
- Variable Technology: The repeller emits waves in constantly changing wavelengths. This intelligent variable technology prevents pests from becoming immune to the sounds, ensuring long-term effectiveness.
- Indicator Light: The red LED light on the unit indicates that the device is actively emitting ultrasonic waves.

4. Maintenance
The Bell+Howell Ultrasonic Pest Repeller requires minimal maintenance. It is designed for continuous, hassle-free operation.
- Keep Clear: Ensure the front of the unit, where the ultrasonic waves are emitted, remains clear of any obstructions such as furniture, curtains, or other household items.
- Cleaning: If necessary, gently wipe the exterior of the unit with a dry, soft cloth. Do not use water, cleaning solutions, or abrasive materials.
- No Chemicals: This device does not require any chemical refills or upkeep.
5. Troubleshooting
If you encounter issues or have questions regarding the effectiveness of your pest repeller, consider the following:
- No Indicator Light: If the red indicator light is not illuminated, ensure the unit is securely plugged into a functioning electrical outlet. Try plugging it into a different outlet to rule out a power issue.
- Initial Increase in Pest Activity: It is common to observe an initial increase in pest activity during the first few days or weeks of use. This indicates that pests are being disturbed by the ultrasonic waves and are attempting to leave the area. This is part of the repelling process.
- Patience is Key: Repelling pests is a continuous process that requires patience. Full results typically become noticeable after 2-4 weeks of continuous use. The process generally follows four phases:
- Phase 1 (Incubation Period): The device begins to work, reducing the pests' sense of smell.
- Phase 2 (Effective Period): Continuous interference breaks the sense of hearing, making pests irritable.
- Phase 3 (Key Period): Decreased survival possibility. The ultrasonic waves affect the nervous system, causing pests to move out.
- Phase 4 (Steady Period): Prevents pests from returning and breeding, ensuring long-term defense.
- Coverage: Ensure you have adequate coverage for your space. Remember, one unit is recommended per room for best efficiency. Ultrasonic waves do not penetrate walls or solid objects effectively.
